I didn't think codes went that high? Check your plugs/wires/coils i assume?
Didnt know what you meant by the codes thing? (at first...getting tired, but thanx)
I did put new delco plugs in it when I purchased the car, but havent done wires yet. Not sure that would set off a code for "EST not toggling", but it would be a cheap investment (wires) Thanks for the responses, I'll keep going after it till I find what it is, the wife wants to drive it pretty bad.
(right) The code triggers immediately on a cold start (after clearing) so I dont think heat is a factor at this point. I'll keep you posted.
